I just came up with this idea. It is an immeasurable but not infinite maze composed of unknown material (which cannot be melted or destroyed in any way), found in northern russia. If any entity goes into the maze it cannot return back, unless under 5m in the maze. Any sonar/radar/trackfinding device fails to function properly, and all electricity is cut off. If anyone were to get a long string, put it on land and secure it to something and go into the maze, when returning the string will lead them to a dead end. Anyone viewing this outside of the maze will be tricked by the illusion of the maze, meaning that the subject who went into the maze will not return, and if they were to check they would be stuck in the maze forever. If 2 entities were to come into the maze, 1 would be at the entrance and 1 in the maze, the entrance will still be there, but will be unable to be accessable by the other entity in the maze. If any direct sight of the entrance were to be broken, the entrance would appear to shift position, which would actually be tricking the brain. Although, looking at the entrance for more than 2 seconds are similar to of that looking at a sun. If a group of subjects were to each take a turn to look at the entrance for it not to shift position would mean that they are wasting their time that the entrance will not shift position, but if sight with another entity is not shared, that entity will shift position without even knowing.

If somebody comes across your article, they're not gonna want to read an entire wall of words. Obviously this is just your proposal, but I was still reluctant to read it all.

As for the idea itself, cool indeed, but seems a bit generic. However I believe with the right twist, it could be made much more interesting. Perhaps, instead of being completely inescapable, there is an exit, but leads to a different time period. This could cause the Foundation to set up an on-site facility to contain the SCP, just so that if any creatures from other time periods don't come wandering into our time.

MrSniker, I just wanted to explain this well with a lot of words, but yeah. Thanks for your advice about this. I could actually add an exit to another dimension? and that the exit isn't visible outside? how's that?

It has some potential but the general idea of an unsolvable maze has been done a million times even the Greeks thought of it https://www.greekmyths-greekmythology.com/myth-of-theseus-and-minotaur/ «« the myth. I'd reccommend putting a spin on the idea like having a monster in the maze or have the maze be alive and whoever enters it gets eaten. But I is noobie so i don't know
